I use an AppleTV2 to access HBO Go on my LD520. Other STB's may offer HBO Go as an option as well. However, you do know that you have to subscribe to HBO to use it on devices such as AppleTV2, Kindle, phones, etc. It's not a free service. Subtitles on Netflix may be dependent upon the device you use as well.

Right, of course I subscribe to HBO. I'm pretty sure I can do the same with ChromeCast. I'll give it a go!

Reviving an old thread. I've had my 42LD550 for over 3 years now and I've loved it. I got awesome calibration settings right out of this very thread when I bought it. Unfortunately in the last few weeks the HDMI ports seem to have a problem. I've been troubleshooting it and it doesn't look good. Here's what I've found:

The Direct TV box works on any of the 4 hdmi ports with any of my cables, but after 10 mins or so will start to flicker and eventually go black with just audio.
My PS3 and XBox360 will not get any video/sound at all. When I turn them on I still get the 'new input device has been detected', then it tries to connect and says 'no signal'. These have worked for years with no issues. I've swapped to known working cables and switched hdmi ports with the same results.
DVD player gets the same result.
I just bought an Xbox One and it does the same as the other 2 gaming units and the DVD player.

I also have an LG projector. If I attach any of the devices with any of my hdmi cables to the projector, they work fine.

Anyone have any idea how the hdmi ports went bad on my tv or how to correct? It's very strange to me that the DirectTV box sort of works but nothing else will get a signal at all. I was hoping the kids could play the new Xbox for xmas but I think I'll have to get new tv over the weekend.

I have the same problem as kmor. But none of my HDMI ports work at all. The other ports are fine. It says "connecting" and then goes to "No Signal". Everything else works fine, I can watch Netflix, etc. I've tried to update FW and reset the system, but no luck. Anyone know how to use the diag port? Is there some way I could tell that the board is toast? Would rather try debugging first before looking for a new display.

FWIW I have the LD520 and it is running and looking like it did right out of the box. I only use HDMI 1 because everything else goes thru the receiver. Occasionally I may us another port if I want to connect something else but it's always worked. The Diagnostics Port is just that, for diagnostics by a certified technician. I've only heard of one person messing with that and they ended up buying a new tv.

I've been reading this forum for some quite time, but just registered today. We bought a 42LD550 when it came out about 5 years ago, and it has performed flawlesly until last month when it ran into the very well known "HDMI No Signal" issues; the other inputs remained unnafected as other users commented. Based on my research there's no other way to solve this issue than replacing the motherboard EBT60932317 ($229 + TAX + S&H in Amazon), so we bought a new one, I just replaced it yesterday and voilá!, HDMI again. The card came with newer cables so I took the time to replace them as well, the process it's very simple and straightforward, perhaps it's same solution any TV technician would recomend when running into these kind of problems, but a lot cheaper if taking the DIY route of course; it doesn't even need a firmware update. The only drawback it's the high price of the new part which made me think for a brief moment if it was worth to fix a 5 year old TV or buy a new one, but 4k and such are not in my budget plans in the near future.

I , too, have been reading this forum thread for as long as it's been here. Posted a couple of times but mostly gained an enormous amount information and so many bits and pieces regarding my LG 42LD550 I am eternally grateful to those stalwart posters and thread starter.
MY LD550 has also performed flawlessly over the years, I got it brand new as soon as it was reviewed. I just happened to be looking for a new tv at that exact time and was lucky, so far.I had been looking around for the potential upcoming costs I would need to prepare for (in the DIY category) ; anyone can call the tech.
I really appreciate you for the time you took to post this experience as I am preparing for the eventuality of the motherboard failure as a bad case scenario-I do not know, yet, what a worst case might be. I saw the Amazon listing for a capacitor replacement kit for about $16 (at this time) for the screen issue the LCD alternatives LD42550-UD is how it is listed there
I have racked up lots of hours on this, way beyond the "normal" so am far nearer the maximum guess of how many hours these are good for-which is for the screen , I think. So, seeing these posts really only make me feel better psychologically, but in reality, something other than what i plan for or expect to go will necessitate a new model in the end.
But,
Thanks anyway

I searched, but couldn't find a thread discussing the 2015 LF6300 model TVs. So, hope you don't mind if I try my question here. The spec sheet says this TV has an RS232 input. However, I can't seem to locate this input. I've tried contacting LG support, but have been frustrated by promises to "get back to me with an answer" but never hearing from them again.

Anyone have an idea where this port is located on the TV? FYI, my goal is to connect to a home theater control system (iPad running Roomie Remote).

Google rs232 mini jack. It looks like a 3.5mm headphone plug on one end and a standard serial cable on the other and will plug in to the "service only" port on the back of the TV.

Yes! Thank you SeldomSeen31!! In chatting and emailing with multiple LG support reps, none of them were able to give me that answer!

I have now managed to get the cables that I need. However, I can't figure out what the correct serial settings should be (flow control, parity, baud rate, data bits, stop bit, crossover). Any idea? Again, I've inquired directly with LG, but no reply.
